It is widely acknowledged that enterprise resource planning (ERP) systems suffer from complex user interfaces. The complexity of these user interfaces negatively affects the usability of these systems. Current research has shown that a need exists to improve the overall usability of ERP systems. This research proposes the use of adaptive user interfaces (AUIs) as a means of improving the overall usability of ERP systems. Research has shown that AUIs are capable of improving system usability by reducing user interface complexity and improving the overall user experience. The primary objective of this research was to determine how AUIs could be designed to improve the usability of ERP systems. An adaptation taxonomy, ERP system architecture (incorporating an AUI), a set of AUI components and a set of usability heuristics for ERP systems were proposed to support the design, development and evaluation of AUIs for ERP systems. The proposed adaptation taxonomy provides support for three types of adaptation: content adaptation, presentation adaptation and navigation adaptation. The proposed ERP system architecture is a three-tiered system architecture, consisting of a Presentation Layer (incorporating an AUI), an Application Layer and a Database Layer. The proposed set of AUI components comprise a user model, a task model and a dialog model. The set of proposed usability heuristics aims to identify usability issues of ERP systems within the areas of Navigation, Presentation, Task Support, Learnability and Customisation. An AUI prototype was developed based on selected adaptive techniques from the proposed adaptation taxonomy and selected components from the proposed system architecture. All of the proposed AUI components were implemented. The AUI prototype was developed for an existing ERP system, namely SAP Business One (SBO). This prototype was designed, in order to resolve the usability issues of SBO identified through the use of the proposed set of heuristics. The development of the AUI prototype was made possible through the use of a software development kit (SDK) provided with SBO. The AUI prototype made use of content adaptation, presentation adaptation and navigation adaptation in order to address the identified usability issues. An empirical evaluation was conducted on the AUI prototype to determine whether it provided any usability benefits over the standard SBO system. The results from the empirical evaluation revealed that the AUI presented usability benefits with regard to learnability and satisfaction. Users who used the AUI prototype were able to learn how to use the ERP system a lot quicker and were more satisfied than users of the standard SBO system. The successful implementation of the AUI prototype provided practical evidence that the proposed adaptation taxonomy and the proposed system architecture can be implemented. This research has provided empirical evidence that the use of AUIs can improve the usability of ERP systems. Future research has outlined several possibilities to utilise and enhance the proposed adaptation taxonomy, the ERP system architecture and ERP heuristics, for the purpose of furthering research within the area of AUIs for ERP systems.

Formal methods are increasingly accepted for developing software systems, however their application to user-interface development is less common. In this thesis, we demonstrate the utility of formal object-oriented techniques for specifying, designing and implementing user-interfaces. The specification of a user-interface describes user-perceivable operations and information structures for an interactive system in an implementation-independent way. Operations of a user-interface specification define tasks. User-interfaces can be specified by a system of communicating agents where some agents are presented to users. An agent and its presentation together define an interactor. Defining the presentation of interactors is a design concern. Widgets are common re-usable interactors for which the presentation is usually well defined. Definitions of widgets may be stored in a library. We illustrate the characteristics of notations for interactor based specification using the Object-Z language and demonstrate using interactors from a widget library. Formal methods enable a "model-based" approach to be taken to the development of user-interface designs. A specification in terms of widgets is derivable from an abstract interactor-based specification. A corresponding user-interface design is usually easily identified from a widget-based specification. Interactor-based user-interface designs can be used to define an architecture for a corresponding system implementation. Derivation of a widget-based specification from an abstract specification corresponds to a task decomposition (i.e., the abstract and widget-based specifications enable the same tasks to be performed, although the operations involved differ). Task decomposition defines a compatibility relation between user-interface specifications. We give "specification patterns" to assist incrementally transforming an abstract user-interface specification to an equivalent specification in terms of widgets.
